I was taking sulfonil 2 capsules on waking, 1 capsule 5-6 hrs later and 2 capsules before bedtime. I took it for about 7-10 days. I had some irregular bowel movements and it progressed to the runs, like water. I stopped taking completely for 10 days. My bowel movements return to normal within a few days. I reintroduced it to my system. I took 2 capsules, within hours my bowels got loose and finally total runs,like water running through me. So, why is this happening?
